I think there was a bug for some people where the control centre icons got randomly shuffled around, especially after reboots.
Luckily, I've not had that happen (iPhone 11) and I have one CC screen dedicated to Hue/Homekit scenes and lights.
I don't use the Home app as I really don't like the way it shows scenes, and have to scroll to see them all. I find the GUI absolutely awful. Like it was knocked up as a demo by someone who would rather be doing something else and then abandoned.
The "torch" icons are shortcuts to the Philips Hue app as I have an Ikea smart plug that works with Hue but not with Homekit. The power icon is also a shortcut to the Hue app and turns everything off. Luckily, my layout hasn't changed since iOS 18 started, apart from the fact in B3 I was able to shrink some homekit icons down to 1x1 and add some more stuff.
